Safety Stop Switch Detects Cable Breaks

The “Broken-Cable” version of the Model RS series of cable-operated safety stop switches incorporates a detection device that signals whenever the actuation cable is severed or pulled. The Model RSB was developed to meet the stringent requirements of safety agencies worldwide. This control is designed to act as an emergency stop for conveyors and other moving machinery. The Model RSB is a “double-ended” unit and has an external extension spring at the end of each cable run, which maintains constant tension on the pull cable. The spring also helps to compensate for expansion and contraction of the pull cable due to temperature fluctuations. The operating handle is held in the vertical position. If the cable is pulled or the cable breaks, the handle rotates and activates the micro switch. In this way, the alarm signal is generated for both conditions: cable pull or cable break. The operating handle must then be manually reset back to the center position after the problem has been corrected.
